As the winner of the last four majors, the No. 1 ranked Serena Williams is unquestionably the best player in women’s tennis.
With 21 major wins and counting—trailing only Steffi Graf’s Open-era record of 22—she may very well end up being regarded as the best women’s tennis player ever. Only time will tell.
But that her latest major sweep (she also won four straight majors in 2002–03) is coming at a relatively advanced age is even more remarkable. She'll turn 34 in late September.
When she topped Garbiñe Muguruza in the Wimbledon finals last month, Williams became the oldest major winner on the women’s side—besting Martina Navratilova, who won Wimbledon in 1990 at the age of 33 years and 8 months.
